Website performance monitoring is the continuous process of tracking, analyzing, and optimizing a website’s speed, uptime, and functionality to ensure a seamless user experience. It uses tools to measure key metrics—like load times and server responsiveness—to identify bottlenecks, prevent downtime, and improve SEO, ultimately boosting user satisfaction.
Key Components and Metrics
Uptime Monitoring: Checks if the site is active and accessible.
Real User Monitoring (RUM): Tracks actual user interactions to analyze performance across devices, browsers, and geographies.
Key Performance Indicators (KPIs):
Largest Contentful Paint (LCP): Measures loading performance (ideal: < 2.5s).
First Contentful Paint (FCP): Time to first text or image (ideal: < 1.8s).
Cumulative Layout Shift (CLS): Measures visual stability.
Interaction to Next Paint (INP): Measures responsiveness to user input.

Best Practices
Automate Checks: Set up alerts to immediately notify you of downtime.
